Description
Technical field
The utility model relates to airfield aid tool product, is precision approach path indicator, especially a kind of precision approach path indicator of novel lamp cup structure.
Background technology
Common known precision approach path indicator (PAPI) light fixture, a light fixture is divided into three lattice, and each lattice is an independently optical unit.Independently optical unit is respectively by a light source, a reflector for each, and a colour filter and lens constitute, and have three relatively independent optical units in the final complete PAPI light fixture.The major function of PAPI is that the second-mission aircraft driver enters runway according to the correct nearly angle of advancing, and guarantees navigation safety.
Colour filter, light source and catoptric system that the disclosed a kind of novel precise sea-way entering indicating device of Chinese patent Granted publication CN2871379 for example, its each optical unit comprise simple lens, be positioned on the focal plane constitute.Light source adopts 200W, 6.6A based on halogen bulb, and catoptric system adopts the rafifinal reflector.
Mainly there are the following problems for each independent light block learn in this PAPI light fixture:
1) conventional light source adopts the based on halogen bulb of 200W, cooperate reflector, beam reflection is gone out, but this mode light efficiency is low, heat is big, and the plated film layer of reflector absorbs photo-thermal, and the plating of plated film layer is inhomogeneous and heat absorption inhomogeneous, cause the plated film layer to damage easily, reduce the service life of reflection shield;
2) general lens diameter is about 110mm, is unfavorable for processing, because lens have two faces, and a plane and a prism sphere, and more little being easy to more of prism diameter processed;
3) light beam of PAPI light fixture is made up of white light and ruddiness, and the centre is the transition region of red white secondary colour, according to International airport navaid light fixture specification requirement, transition region need≤3 ', existing optical system is difficult to reach this standard because have only lens, is unfavorable for airport security;
4) the fixing of light source mainly taked directly bulb to be inserted support, utilizes shell fragment that bulb rack is fixed in the reflector middle position then, rocks because of the space between shell fragment and the bulb rack causes support, and light source also waves thereupon, causes the light source location inaccurate;
5) after reflector reaches service life, as untimely replacing, then be unfavorable for the beam reflection effect, influence light intensity, increase dangerous, but the replacing of reflector bothers very much, could change after needing the professional that light fixture is disassembled.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of precision approach path indicator of novel lamp cup structure, can effectively improve light efficiency, and littler red white transitional region is provided simultaneously, improves airport security.
The utility model solves the problems of the technologies described above the technical scheme of being taked: a kind of precision approach path indicator of novel lamp cup structure, optical system unit by three separate optical system that are provided with in a shell and the shell constitutes, wherein, any optical system unit constitutes by Lamp cup, two lens and a filter disc, the Lamp cup inboard is provided with light source, and the light that is penetrated by light source penetrates by first lens, filter disc, second lens successively.
At each optical unit independently, the utility model is by increasing lens numbers, constitute the novel lamp cup structure, add and being used in combination of Reflecting lamp cup, solved the control range of the red white transition region of PAPI light fixture light beam better, meet International Civil Aviation Organization's annex 14 the 4th edition (International Civil Aviation Organization Annex14), The People's Republic of China's standard GB/T 7256-2005 satisfies the security needs that the airport increases day by day.
Twin-lens use, it is better that the light beam imaging was imitated, transition region is littler, meet≤3 ' requirement, more help airport security, and make the reduced of lens, overall volume is also corresponding dwindles.
A described separate optical system construction unit also comprises a Lamp cup support, and the Lamp cup support is fixed in the shell, and Reflecting lamp cup is inserted on the Lamp cup support fixing.
Concrete operation method is: through calculating the distance of determining between each parts, at first locate the Lamp cup support, again Reflecting lamp cup is inserted support and fix, replaced the form that original light source adds reflector with Reflecting lamp cup, carry out the light source location; In the place of distance Lamp cup setpoint distance first lens are installed afterwards, in place colour filter is installed again apart from first lens settings distance, second lens are installed at last again, form a Reflecting lamp cup, a colour filter, two optical units that lens constitute, the beam angle of assurance product, light intensity, color, transition region etc. meet the international technology standard.
Described Reflecting lamp cup is 105W, the 6.6A Reflecting lamp cup.The characteristics of general incandescent lamp are that power is high more, and light efficiency is low more, and heat energy is high more, and the utility model is compared with 200W under the prerequisite that remains unchanged substantially in light intensity, substitute original based on halogen bulb with the 105W Reflecting lamp cup, improve light efficiency and reduce heat energy.
The diameter of described first lens, second lens is 70mm, helps the processing of prism sphere.
Three optical system units are arranged side by side on sustained height, and the Lamp cup of both sides optical system unit inwardly or laterally tilts, and is 2～4 ° horizontal sextant angle with the Lamp cup of intermediate optical system unit.
The beneficial effects of the utility model are:
1, the utility model is by adopting novel Lamp cup structure, increase lens, improve light efficiency and keep light intensity, improve light beam transition region scope, the lens that between light source and colour filter, add lastblock prism sphere, eliminate optical aberration well, make transitional region littler, reach the better effect of white red boundary;
2, twin-lens use, it is better that the light beam imaging was imitated, transition region is littler, light beam is through the adjustment of twice lens, its red and white transition region meets≤3 ' requirement, more help airport security;
3, the reduced of lens is contracted to 70mm by common 110mm, more helps the processing of prism sphere;
4, the optical unit volume integral body of novel lamp cup structure is reduced into intrinsic about 2/3, make the volume of whole light fixture reduce greatly, in the airfield runway zone, often there is the strong wind of following the jet airplane engine, reducing of light fixture volume, make the windward side reduce, make light fixture more stable, and outward appearance is more attractive in appearance;
5, replacing is easy, only need to extract old Reflecting lamp cup, insert new getting final product, reflector is changed in the lump as the part of Reflecting lamp cup, need not light source location calibration, general personnel all can operate, and are very beneficial for keeping the light intensity in the regulation beam angle, when changing Reflecting lamp cup, help keeping the light source reflecting effect;
6, Cheng Shu bulb navigation system need not to adjust focal length behind the feasible replacing Reflecting lamp cup, and whole optical system is more reliable and more stable;
7, replace 200W based on halogen bulb and associated reflections cover with the 105W Reflecting lamp cup, under the prerequisite that light intensity remains unchanged substantially, improve light efficiency, reduce heat energy, have energy-saving effect.
